Re: Foidel Creek Mine, Permit No. C1982-056, TR70, Adequacy No. 2
Dear Mr. Nettleton:
The Division received Twentymile Coal Company's (TCC's) application for a technical revision (TR70)
on November 20, 2009. The Division has reviewed the proposed revision and sent an initial adequacy
letter to TCC on December 30, 2009. Twentymile Coal Company provided adequacy responses on
January 4, 2010. After review of TCC's responses, the Division has the remaining concerns: (Numbering
continues from the initial adequacy items.)
4. Twentymile Coal Company indicated in the Adequacy Response letter, dated January 1, 2010,
that TCC has notified Routt County Road and Bridge Department and is waiting for a follow up
site inspection with a representative from Routt County. The Division spoke with Paul Draper of
Routt County Road and Bridge Department on January 6, 2010. Mr. Draper indicated that
Tammy Crawford would be the County contact for this project. Ms. Crawford contacted me on
January 11, 2010. Ms. Crawford informed me that TCC will need to obtain a "Utility Install
Right-Of-Way" permit before proceeding with the work within the county road right-of-way. She
indicated that TCC will need to provide a site plan and utility locates to her office. Snow pack
and winter weather may slow this permitting process. Please provide evidence to the Division
that TCC has obtained a "Utility Install Right-Of-Way" permit from Routt County Road and
Bridge Department prior to conducting work within the county road right-of-way.
7. Revised pages 4.05-45.19, and 2.05-50.7 indicate that sediment control materials will be used at
any location where the pipeline corridor is within 50 feet of Fish Creek. The reader is directed to
Design drawings in Exhibit 49R for construction and sediment control details. TCC submitted
Figure 1 "Route for 14" HDPE Pipeline from 18L Shaft to existing 12" HDPE line from the Fish
Creek Vent Shaft" (dated 9/18/2009). This Figure shows a general layout of the proposed path
for the 18L waterline. This figure does not show topography, location or designs of sediment
control measures. Previously approved figures in Exhibit 49R depict pond designs and shaft
dimensions for the 18L ventilation shaft and pad. The Division was unable to locate any designs
or drawings of the proposed placement of the sediment control measures proposed for the 18L
waterline construction. Please provide detail regarding placement and design of the proposed
sediment control measures.
